The biography of the teacher of the deaf who, through his knowledge of music, human speech, and hearing, invented the telephone. Bell was a pioneer in many fields that aided communication over distances. He worked tirelessly to help the deaf communicate with others (even Helen Keller came to him for help). After the telephone, Bell invented the photophone (a device that uses a beam of light to transmit sound wirelessly), and developed phonographic sound recording methods.
